1. Blockchain Overview

RECEN is built on advanced blockchain infrastructure that combines the security of Ethereum-compatible networks with high-performance, low-cost transaction processing.

Our technology stack is designed specifically for energy trading, with custom smart contracts for REC issuance, marketplace operations, and cross-chain interoperability.

2. BSC (BEP-20)

The RECEN token is built on Binance Smart Chain as a BEP-20 token. BSC provides: EVM compatibility for Ethereum-based development tools, significantly lower gas fees compared to Ethereum mainnet, high throughput for marketplace transactions, and a large existing ecosystem of DeFi protocols.

3. PoSA Consensus

RECEN leverages the Proof of Stake Authority (PoSA) consensus mechanism with 21 validator nodes. This provides: 1-second block time for near-instant transaction finality, 3-second generation time for rapid certificate issuance, Byzantine fault tolerance for network security, and energy-efficient validation compared to Proof of Work.

4. Smart Contracts

RECNFT1155 Contract (ERC-1155): Manages the issuance, ownership, and metadata of Renewable Energy Certificates. Each token stores on-chain data including energy type, CO₂ per unit, issuer address, and issuance timestamp. ERC-1155 allows multiple REC units to share a single token id for efficient batch minting.

RECMarketplace1155 Contract: Handles listings, partial-quantity purchases, and differential fees for REC trades. Supports USDT (BEP-20, 18 decimals on BSC) and RECEN token payments. Guarded by OpenZeppelin ReentrancyGuard.

Payment tokens (USDT, RECEN) are live BEP-20 contracts on BSC Mainnet (Chain ID 56) — not test tokens.

5. Smart Meter Technology

RECEN integrates proprietary Smart Meter technology for accurate energy data recording. Smart meters automatically measure renewable energy generation and transmit data to the blockchain for verified REC issuance.

This creates a trustless pipeline from energy generation to certificate creation, eliminating the need for manual verification in most cases.

6. Cross-Chain Protocol

RECEN adopts cross-chain technology to enable seamless communication with other blockchain networks including Ethereum, Polygon, Solana, and Avalanche.

Key features: Ethereum-based BEP-20 compatibility, API support for token issuance and integration, decentralized application (DApp) ecosystem, and energy-specific data recording mechanism.

7. Security

Security measures include: OpenZeppelin audited contract implementations (ERC-1155, BEP-20), SafeERC20 for secure token transfers, ReentrancyGuard with checks-effects-interactions ordering on buy flows, Ownable access controls for administrative functions (with a 10% max fee cap), and immutable on-chain data storage for certificate integrity.
